Description: The present specification refers to an automatic mop device for cleaning floors, the purpose of which is to help an user to clean a surface such as a floor, by substantially reducing the own user's effort as it makes easy to squeeze dry a mop or the fringes of a mop, located at the lower end of a supporting stick, such as a broomstick. This invention applies to the industry devoted to the manufacture of industrial and domestic appliances. It is known a large variety of elongated cylindrical shaped bodies having, or not, non-slipping areas on their surface in order to facilitate their use, since the function of these areas is to avoid the stick to slide out of an user's hands, and these sticks are made of wood, wood coated with a plastic film, stiff plastic material, lightened metal, and so on. All these sticks had, at one end, a receiving body, at first, formed by a duster or floorcloth, which, incorporated and bonded in its surface, carried out a cleaning operation, said surface having been previously wetted thanks to the optional cooperation of a cleaning product or detergent. After the first cleaning operation by wetting the surface to be cleaned, the user should remove the duster or floorcloth, squeze it dry, and locate it on the corresponding portion of the stick situated at one of its ends in order to perform the drying operation of the previously water - wetted surface in cooperation with a cleaning product or not. In a most recent date, parts made of a light material have been incorporated in the ends of a stick, said parts having a plurality of filiform elements securely united, made of a textile material being capable of receiving a large amount of water and transferring it to the surface to be cleaned, these devices being known as mops or scrubbers. Subsequent to the first cleaning operation aided by a large amount of water used for performing the surface cleaning, the mop or scrubber was squeezed dry to remove the water carried by it, and then it was necessary to carry out a second operation in order to remove the water from the already cleaned surface. Of course, appreciable novelties have been incorporated in these elements mounted on the stick ends, as for the material, giving them a greater wear resistance, a large amount of water content and, consequently, a higher drying capacity, giving them different shapes, but always having the common denominator of being made starting from a textile material, the main bodies - being formed as a plurality of markedly elongated trips. It has been shown that the industrial and domestic cleaning operations involve, in all cases, a remarkable effort which has been lessened by the incorporation, within the cleaning field, of these sticks that, with the cooperation of a mop or scrubber, achieve a remarkable lessening of efforts and, also, avoid the persons performing a flooring operation to carry out this operation in a position which implies an ardous work, such as, for example, kneeling. At present, nevertheless, in operations carried out to clean a surface starting from a stick and a scrubber mounted on it, the most significant hard work is to squeeze the mop or scrubber dried. In order to perform the squeezing operation, the user must insert the assembly of textile material elements within a body having a reverse truncated cone shape having a plurality of perforations allowing the water to pass inside a carrier bucket, and then to twist the assembly for carrying out the squeezing operation, which, after a certain period of time, causes user's arm and back aches. An obvious solution to the present problem would be to rely on a device, machine or apparatus capable of making easy the squeezing operation of the body former by markedly elongated textile materials, so acting like an automatic mop. The applicant knows the existence at present of a plurality of patents of invention claiming scrubbers generally applicable to carry out industrial cleanings, in which squeezing devices have been provided that, with the cooperation of a manual actuating lever, achieve two bodies to join one other, obtaining in consequence of this union, a sliding, or by a turn, that the mop or scrubber, constituted by elongated bodies of a textile nature, will be squeezed. The applicant knows,also, the existence at present of an European patent applied for under number 0 468 158, in which a squeezing device, configured starting from a body adaptable to the mouth of a bucket having a quadrangular or rectangular plan, is protected and claimed, which receives, after the squeezing operation,the water from this operation, and, at the same time, it uses thiswater for the cleaning operations following the mop squeezing, the body being constituted as a frame or casing, in the interior of which there are a plurality of gears, the function of which is to bond, join or unite two cylindrical bodies arranged in a transverse mode, after an user has operated an external lever, this lever acting as a starting element in a fully manual operation of the different internal mechanisms which, with their motion and turning, manage to gradually free the mop of scrubber from the water incorporated in its structure. Obviously, although this mechanism, acting as a squeezer for a conventional scrubber, combines particular characteristics simplifying the own squeezing operations, requires, on the user's side, to perform a marginal effort to put into operation the squeezing mechanism, by operating the lever; these operations requiring, - even reducing the effort, in a specific manner, to make an effort for operating the rollers. From the patent of invention applied for in USA under number 3.987.513, it is known the existence of a aqueezing mechanism for mops or scrubbers, which joined to the end of a stick or similar, using a body supporting part made of a textile material, allows two electrically driven rollers, aligned in a transverse and parallel position, to gradually move so that, in a continuous way, the end of the body constituting the scrubber, as for the textile material, inserts in the space existing between both rollers, generating, in consequence, the removal of the water carried, so requiring, after the squeezing operation, a reverse operation of the rollers in order to make also easy to gradually remove the filiform material constituting the end of the scrubber, so obtaining that, after the removal of same, the mop or sceubber may be used for carrying out the corresponding drying of the surface already cleaned, by using water in cooperation with a detergent, - soap or any cleaning product. This invention, applied for in USA, is to be incorporated in a markedly rigid supporting body, fitted inside with a large hollow space for receiving the removed water, relying on its surface on an emerging body having a cylindrical configuration, fitted, at its upper part , with an access mouth, on which the mop or scrubber is joined, and presenting at the lower part a slot aligned with the center zone existing between the squeezing cylinders, which are driven by a motor externally arranged, which, in turn, is connected to the mains. Apart from the fact that this squeezing operation requires an insertion, passing and squeezing operation, that is a second removing and releasing operation, which requires a substantial - amount of time, the invention is driven by motive elements externally connected to a motor, this motor being fitted with an external circular crown which acts on a chain moving at least one of the rollers, so that, in cooperation with a filiform body inserted between both rollers, both cylinders, in parallel alignment move, the other roller having springs which sustematically push the stationary roller with the movable roller, so obtaining in consequence the squeezing operation, the apparatus being inexcusably connected, for feeding and driving the motor, to the - mains, which implies a potential danger, since the element to be squeezed is still wet, and although the motor casing is properly shielded and insulated, any anomaly can cause en electric shock to the user. This invention is qualified to start the motor when the mop or scrubber contacts a sensor located on the access ramp toward the rollers. The patent of invention applied for in USA under number 4.344.201 discloses a mop or scrubber capable of being squeezed thanks to the existence of a squeezing body arranged on a bucket or similar receptable, and having, at the lower side, a motor fed by electric power connected thru a cable and pin to a conventional mains, so moving a shaft joined to a hollow truncated cone fitted with a plurality of drillings inside, the turning of the shaft generating the removal of the water carried by the mop or scrubber. Obviously, the acting and removal of the water carried by scrubber will be conveniently removed, but logically this removal of water implies a substantial amount of time for achieving the removal in the strict sense, according to the removal of same like an extractive cyclone, driven by the motor located at its lower portion, and, in addition to this loss of time - characteristic, it should be noted that the simple connection to the mains, connection which independently of its protection, insulation and other safety elements, can cause an electric - shock to the user. From the above, it is clearly confirmed that, although the inventions covered by the above mentioned patents of invention operate substantially reducing the operations required to be carried out prior to the development of the objects covered by the patents in question, they do not fully alleviate same, even presenting some inconvenients inherent to their particular characteristics, in regard to the safety. A suitable solution would be to rely on the existence of an apparatus that, configured like a scrubber in the strict sense, could allow the water carried by the fringes of a mop or scrubber to be removed, the squeezing operation being carried out in a simplified manner, starting from the use of a motor automatically driving the direct acting elements on the flanges, but, at the same time, reducing the operating times according to the direct applications on the own fringes constituting the cleaning area of the surfaces, this operation being implemented by the actuation, on the active elements, of a motor which, fed by electric power does not present any problems of potential accidents. Nevertheless, up to date nothing is known about the existence of a device having the desired features for this purpose, SUMMARY OF THE INVENTION The improved automatic mop device for cleaning floors as proposed by the invention is constituted per se as an evident novelty in the frame in which it is incorporated, and it can be considered as a solution to the squeezing problem of a body made of trips in a textile material used for cleaning and later drying a surface. In a more specific manner, the improved automatic mop device for cleaning floors is constituted starting from a stiff platform provided with wheels facilitating its displacement, a portion of this platform being destined to incorporate in it a mop bucket, and, also placing on the upper portion of the platform and,specifically, where the bucket is situated, a hinged arm. On the upper side, a handle has been provided, the function of which is to make easy the device transport, and, at the same time, and owing to the existence of a polarity reversal switch located at one end thereof, an electric circuit is made, enabling a 12V motor which is fed by a direct current, the making of the circuit being attained when performing the operation of squeezing the textile fringes. This motor drives a series of speed demultiplying gears, and, at the same time, a power mutiplier, so obtaining both the speed and power which are necessary for operating a series of vanes - squeezing the water carried by the mop body textile fringes. The electric feed of the motor for operating said vanes is obtained from a battery located on an adequate frame situated above the wheels carrying the frame and bucket. Said battery can be charged directly from the electric network by means of a portable battery charger. The electric motor is specifically designed for limiting its operation for a short period of time, during which said vanes - perform the fringe squeezing, the limiter being configurated as an end of stroke switch which reverses the polarity to the motor, so shifting its turning sense. Once the fringes have been squeezed, the vanes return to their rest position. Of course, when the vanes recover their rest position, they are ready to start again the squeezing operation of the fringes so many times as required, by means of the person performing the cleaning operation upon pressing the switch located at the mop stick. The invention features a main switch connecting and disconnecting the current intake to the motor, and it avoids, consequently, the vanes to act, having a 12V battery and relying on a 15 amp fuse in order to prevent overvoltages. The end of the main switch and the end of the fuse are connected with the switch located at the handle, the end of which is - linked, in turn, by connection, to the end-of-stroke switch, limiting the course of motion of the motor driving the squeezing vanes. During the operating time, the motor is given a possible direct current in a sense, during which the vanes move and squeeze, but, nevertheless, during the rest time, the motor receives the current in a reverse sense, only the time necassry for allowing the squeezing vanes to move back until recovering their rest position. This rest position recovery being performed in a very smooth way in order not to damage the gears moving them. The 12V battery, the switch and the fuse are mounted in series. As described in more detail in the descripcion of the preferred embodiments of the invention, the mop device can be shaped starting from a conventional bucket fitted with a squeezing area and on which, a squeezing head is located, this head being fitted with adequate vanes driven by an electric motor that, in cooperation with gears, fuses, battery and switches, drives the vane after pressing a push-button that, linked with the switch, moves said vanes in accordance with the pressing performed by the mop stick, with no need for the mop's user to directly press the push-button as by simply pressing down the latter, the squeezing vanes are set in motion. As also described later, the mop device can be fitted with a press squeezing system driven by two asymmetrical arms located on either side of their inner area, being incorporated inside the frame fitted with adequate characteristics to be located on the upper side of a bucket, two motors which are automatically driven by the own user by simply pressing down a push-button starting said motors and, consequently, the squeezing arms. Lastly, the mop device can be fitted with a magnet to be located in an appropiate area of the mop stick or handle. Said magnet sets automatically the squeezing vanes in motion when it approaches the contact point next to the squeezing basket. BRIEF DESCRIPTION OF THE DRAWINGS.

PREFERRED EMBODIMENTS OF THE INVENTION. From Fig. 1, it can be seen the manner in which the improved automatic mop device for cleaning floors 1 is constituted, starting from a base 2, preferably made of a stiff material, configured as a platform having wheels at the bottom side thereof 3, the function of these wheels being to make easy the assembly transport. On the platform, there is incorporated a casing 15 housing a motor, mechanisms and feeding battery of the own motor, while on the other side of the casting, a conventional mop bucket 4 is mounted. The mop device 1 has a hinged arm 7 with a joint point 16, a handle 13 and a sliding tube 8 located next the handle or holder 13. The casing is fastened to the frame or base 2 by means of conventional screws 11. The casing has a connection intake 10 for receiving the cable of a charger from which the 12V battery is charged. This battery is located within the casing, thru which the motor is fed. In the same way, this side of the casing has an intake and connection 12 for a 15 amp fuseholder, and also a switch 14 for starting the mop. In the inner center part of the casing, an arm 5 is installed at the lower middle part of which a squeezing element 9 is located, formed as squeezing vanes. which is inserted into a cavity existing in the upper side of a bucket 4, to be used as a squeezing element of the scrubber or mop fringes. The arm 5, specifically in its external upper zone, has a support 6 to which the mop stick is fixed. The motor drives an assembly of speed demultiplying gears,and, in turn, a power multiplier, so obtaining the adequate speed and power necessary to said arm or vanes 9 for squeezing the mop fringes. The motor is fitted with an end-of-stroke acting thru a small notch that opens, and when the end-of-stroke is effected, it reverses the polarity to the motor, thereby the arm 9 returns to its - rest position. Then, the squeezing operation is started again so many times as required. In turn, the end-of-stroke switcj limits the course of the motor driving the squeezing arm. Figures 3, 4 and 5 show different views of a second embodiment of the invention, referred, in general, as 20, which is constituted starting from a bucket 22 made of any material, situated on the upper surface of a support and translation part 23 fitted with free turning wheels 24, the bucket 22 having a handle or holder - 26, knurled at its center position to make easy its grasping and adherence to the user's hand. A squeezing head 25 is mounted on the bucket 22 by conventional means, which is formed by a casing housing an electric motor, a shaft, gears, a battery and a relay (not shown in the figure, as they are conventional elements, coupled one other in order to achieve the purpose of driving squeezing vanes), the function of the motor being to receive the battery or accumulator current after an external switch 29, located within a notch 28 having a semicircular arc shape, vertically situated, is pressed by the handle or holder of the mop with a ligtht pressure, a relay acting once the switch 29 has been operated, giving the appropiate orders to the inside of the squeezing head with the purpose of causing the motor to act, starting to turn, and setting in motion a shaft acting on the squeezing arms or vanes 27, exerting a pressure on the mop or scrubber located within the basket acting as a filter 30, squeezing the content of water from the mop, this water passing inside the bucket 22, the dirtiness potentially dragged by the mop during the cleaning or washing operation on the surface, resting on the surface of the filter 30. Once the turning has been effected, the shaft, acting in cooperation with the gears due to the fact that it is fitted with a notch acting as end-of-stroke, stops the motion of the squeezing arms or vanes 27, and the presioning operation on the mop by means of the squeezing vanes or arms 27 can be repeated upon acting again on the switch 29, turning the motor fed by an electric current obtained from the battery or accumulator, and commencing again the cycle. The bucket 22 has, on its upper edge, a diametrical trimming stiffing it in order to allow a coupling of the squeezing head 25. The squeezing head 25 has, in its external portion, exactly on one of its sides, a light pilot 34, showing every moment that the battery or accumulator incorporated inside the squeezing head 25 is being charged by means of an electric current intake configurated as a flexible cable having, at one of its ends, a female pin incorporated in the intake 35, while the other end of the cable has a male pin connected to a conventional electric power intake. Also, the squeezing head 25 has a pilot 31 to be lighted on when the lighting switch 32 has been actuated, this switch allowing - that, by operating the grasping element or handle which carries the mop, exactly by the pressure exerted by the user and through the stick on the switch 29, the arms 27 act, squeezing the water carried by the mop and dropping within the bucket 22 thru the bascket or filter 30. Lastly, it should be pointed out that the mop device is fitted with a protection fuse 33. As a complement to the description made on the second embodiment, it should be noted that once the cleaning operations have been ended, the squeezing head 25 can be removed from its operational housing, and once the bucket 22 has been duly cleaned up, the squeezing head 25 can be housed within the bucket 22, occupying a minimal space. Figures 6 and 7 show a third embodiment of the invention, which has been referenced in a general way with 40, and being constituted starting from a casing or frame 42, on which all the acting mechanisms of the object of the invention are placed, and this assembly of frame or similar 42 being placed on a conventional bucket 43 by using anchoring links 59 located on the back - side thereof, and having lateral projections emerging from steps 60 formed or located at the lower part of the main part. The frame or casing 42 is located on a bucket 43, and this, in turn, is placed on a transport carriage 44 fitted with appropiate wheels 45, and it can optionally carry a basket 47 to contain auxiliary elements for cleaning purposes, such as a spare mop, the basket being installed on the vertical arms of handle 46, which facilitates the motion of the assembly composed of a bucket carrying the squeezer on its upper mouth and fixed to one of its - side branches. As can be seen in Fig. 6, the squeezer has a retaining link for the mop holder 48, fixed to a front area, presenting a center recesss on the upper portion 50, fitted with a switch thru which and with the assistance of the mop o scrubber stick, a light pressure is exerted on said switch,setting automatically in motion the motors in a sense or other, according to the turning of the current obtained from the battery and being determined by a relay driven by said switch 50, and thanks to the cooperation of an end-of-stroke switch (non referenced). When the operating switch 50 is enabled, that is to say, when it is subject to the tool and handle or holder of the mop or scrubber pressure, the motor will run in the desired sense, moving the gear assemblies and these latter, in turn, will move the arms 51 and 52, performing the pressing or squeezing operation, so achieving that the arms 51 and 52, when approaching one other, squeeze the mop or scrubber, the water falling towards the lower zone, - passing thru a grating 49, which collects the refuse of the materials caught by the mop, and the water, now practically clean, pass into the bucket 43 on which the assemby is installed. As can be seen in Fig. 7, the invention relais on a lighting - pilot 54, a main switch 55 and a rapid access protection relay - 56, located on one of the back sides of frame 42, while on the opposite side, a charge indicator pilot 57 is installed, which acts as an indicator for the electric power fed by the battery (not - shown) through a conventional cable 53 plugged in a plug located at the squeezer, and having the other end connected to a conventional socket linked to the electric network. The side vanes of support 60, located at the lower part of the frame or casing 42, can optionally have two emerging stubs 58 to be duly engaged on the side walls of bucket 43, exactly on the upper inner zone thereof. In Fig. 8, a fourth embodiment of the invention is illustrated, with general reference 70, which is constituted, as in previous - cases, starting from a bucket 71 made of an appropiate material having a plantar rectangular shape and having all its vertices rounded, presenting, at its upper portion, a perimetral oversized edge acting as a reinforcement link of the own bucket 71, allowing-to fix on same a body 74, inside which all acting elements of the - object of the invention are incorporated. The bucket 71 has a handle or holder 75 and it is situated on a platform 72 provided with free turning wheels 73 to make easy its transportation and avoid the user to carry out efforts during the cleaning operations. On the perimetral edge of the main body of bucket 71, a body containing mechanical and electric elements 74 is installed, having a basket 79 presenting a plurality of perforations in order to allow to pass the water taken out from the mop or scrubber, the main body 79 having a reverse truncated cone shape and with inner vanes 76 acting to perform the mop or scrubber squeezing, these vanes 76 being moved by the motor located in the frame or casing shaping the body 74. On the upper portion of the main body 74, frame or casing, a pilot light 80. a main switch 81, a fuse holder 82, an indicator 83 are arranged, the function of said indicator 83 being to inform the user about the necessity of recharge the battery located inside, by engaging a feeder in the base of socket 84. In syntesis, the automatic mop device, by means of the vanes 76 emerging from the inner walls of basket 79, squeezes the fringes - emerging from the mop stick (shown in Fig. 9 with no reference), the vanes 76 exerting an adequate pressure to attain a full squeezing of same. Owing to an inner circuit which operates when the mop is inserted into the reverse truncated cone shaped basket 79, and by simply approaching the stick of the mop or scrubber to the front end of frame, the stick, fitted with an inner magnet 85 adequately dimensioned, sets in operation the inner circuit which has a timer which operates for an adequate time the squeezing vanes 76, this operation being enhanced with regard to the inner circuit by a microswitch.
